SAFETY DEVICE FOR PIPING.

Specification of Letters Patent.

Patented Jan. 4, 1910.

Application filed May 15, 1907. Serial No. 373,847.

To all whom it may concern:

Be it known that I, JOHANN KonNIG, a subject of the King of Bavaria, residing at 97 Alexanderstrasse, Riga, Russia, have invented new and useful Improvements in Safety Devices for Piping, of which the following is a specification.

My invention relates to means for remedying in rapid and simple manner the inconveniences attending bursting of a wateror other pipe. For this purpose devices are provided, whereby the defective part of the pipe is cut out by means of a branch-pipe. irccording to my invention I place in lines of piping pairs of valves with a junction casing between the members of each pair of valves, the junction casing being adapted to be connected to a branch pipe in the event of the main pipe bursting. Each junction casing is also provided with means for connecting it to a hydrant.

The invention is illustrated in the accompanying drawing, in which the figure is a plan.

a is a portion of thepiping, b b are two man-holes located at certain distances apart and containing the devices for connecting a branch-pipe c. The devices consist of pairs of valves (Z c, f g, with a casing h, 2', between each pair, for connecting the branch 0.

Assuming that a pipe has burst at :0, the

four valves d e, f 9 must be closed and the branch 0 connected to the flanges of the cats ings h, 2'. The valves (Z, g, can now be opened again, the burst pipe being thus cut out and the passage of flow in the piping maintained through the branch-pipe c.

In the drawing, the casings h, 2' between the valve (Z c, f g are shown as being provided each with an additional flange 70, m, for connecting a hydrant.

The branch-pipe 0 may be an ordinary rigid pipe, or a flexible metal pipe. The valves may be of any suitable description whatever, whether with lifting or sliding action, cocks, or the like.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is The combination with a continuous pipe, of pairs of valves in said pipe, a casing between the members of each pair of valves, and a branch pipe connectible with said casings in case of bursting of the first-named pipe, each casing being provided with means for connecting a hydrant.

In witness whereof I have hereunto signed my name this 29th day of April 1907, in the presence of two subscribing witnesses.
